"Because you fought alone the romulans, you've become twice worthy of sto-vo-kor".

chay' mu'tlheghvam vImughlaH? chay' mu'tlheghvam "twice" vIDellaH?

The twice isn't literally true, unless you mean you've done exactly two things to be worthy of Sto-vo-kor.

nIteb romuluSnganpu' DaSuvpu'mo', Suto'vo'qor Dabajqa'pu'

Or if twice is literal,

nIteb romuluSnganpu' DaSuvpu'mo', cha'logh Suto'vo'qor Dabajpu'.
